Just answered my own question, I received the SS tubes in the post today and there exactly the same size as the plastic ones so if anyone is interested you can buy these with confidence for your hobby stuffer, nice quality as well, that's me stuffing this weekend.

I have been trying to source some stainless steel stuffing tubes for my hobby stuffer, I looked on the Weschenfelder site and enquired what the diameter of the flange was?? i.e. the wide bit at the end where it connects to the stuffer. Rob at Weschenfelder was very helpful and informed me that the flange was 50+ mm(cannot remember the exact size) Unfortunately my hobby stuffer requires a flange diameter of 38-40mm. Petit - if you read this message, would you mind telling me what size of flange is on the S.S. tubes you bought, if they are 40mm I would like to buy some as well.
